thanks a lot for the reply but that was not my question.
i know how much ram 32bit addresses. I just ask if there is way to decrease the ram windows uses when its idle
If u will get it down, it will start to choke and freeze.
Best advice would be to get more RAM and W7 x64
2nd Best advice would be to remove all the apps that u don't use
and stop processes to apps like iTunes and such.
Not to disable them, just to make them start in "manual" mode, so u don't restrict usage.
